[0002] In the electromechanical construction of steel structure workshops, steel structure workshops with crane beams are widely used in industries such as machinery manufacturing and heavy industry due to their advantages such as high space utilization and strong load-bearing capacity. In such workshops, electromechanical installation projects need to coordinate with the structural layout of the crane beams to complete the cable tray laying to realize functions such as power transmission and equipment control signal transmission. Existing cable tray installations mostly use a combination of fixed brackets and expansion bolts. Once the brackets are fixed to the wall, ceiling, or steel structure with bolts, their support angle cannot be flexibly adjusted. When it is necessary to adjust the angle of the cable tray to change the cable routing, the construction personnel need to dismantle the original brackets and re-drill holes for installation. This not only wastes a lot of manpower and time costs and causes secondary damage to the building structure, but also significantly increases safety risks due to repeated dismantling and installation operations. Therefore, this utility model proposes a cable tray installation device. Utility Model Content

[0022] Embodiment

[0023] As Figures 1 to 3 shown, an installation device for a bridge frame proposed by the present utility model includes: an installation rib plate 1, which has good load-bearing performance and anti-deformation ability and can stably carry the weight of the entire device and the bridge frame. A plurality of first through holes 9 are opened on one side thereof, facilitating the adjustment of the installation position according to actual installation requirements. A plurality of insertion holes 2 are opened on the installation rib plate 1 to ensure that the subsequent insertion bars 4 can be smoothly inserted without excessive shaking. A frame 3 is provided on one side of the insertion hole 2. The frame 3 is arranged in a "C" - shaped structure and is made by an integral molding process. It not only has a light weight but also can provide stable support. It can be designed into multiple models according to the width specifications of common bridge frames to adapt to the installation of different sizes of bridge frames. An insertion bar 4 is fixedly arranged on the frame 3. The insertion bar 4 is fixedly connected to the frame 3 with reliable connection strength, and the insertion bar 4 can be inserted into the insertion hole 2 to quickly disassemble and assemble the frame 3. A second through hole 10 is opened on one side of the insertion bar 4. The second through hole 10 matches the specifications of the first through hole 9 to ensure that the installation bolt 11 can pass through smoothly. An installation bolt 11 is arranged through between the first through hole 9 and the second through hole 10, and it is equipped with a nut and a washer, which can effectively prevent the nut from loosening, limit the stable installation of the insertion bar 4 on the installation rib plate 1, and ensure the stability of the connection between the frame 3 and the installation rib plate 1. A guiding through groove 12 is opened on the bottom surface of the insertion bar 4, and the inner wall of the groove is processed to reduce the frictional resistance during subsequent sliding.

[0024] Furthermore, a sliding plate 5 is slidably mounted on the bottom surface of frame 3. The surface of the sliding plate 5 is treated to improve wear resistance and smoothness. The size of the sliding plate 5 is adapted to frame 3, ensuring flexible sliding within frame 3. Sliding grooves 13 are formed on both sides of the sliding plate 5, which are slidably connected to guide grooves 12. The sliding grooves 13 and guide grooves 12 are precisely matched, allowing the sliding plate 5 to slide stably on frame 3 and preventing deviation during sliding. A guide groove 14 is formed on the inner wall of the sliding plate 5. The shape of the guide groove 14 is consistent with the shape of the subsequent limiting plate 68, ensuring a tight fit and sliding. An adjusting screw 7 is threaded through one side of frame 3. One end of the adjusting screw 7 is rotatably connected to the sliding plate 5 via a bearing. The bearing has good performance characteristics, allowing the sliding plate 5 to slide on frame 3 by rotating the adjusting screw 7, thereby adjusting the position of the sliding plate 5 and providing a basis for subsequent cable tray installation angle adjustment.

[0025] like Figures 3 to 5As shown, the sliding plate 5 is equipped with an adjustment assembly 6 for adjusting the installation angle of the cable tray. The adjustment assembly 6 includes a sleeve block 61 that is movably fitted onto the sliding plate 5. This sleeve block 61 possesses good toughness and strength, and its inner wall has a reasonable gap with the outer wall of the sliding plate 5, ensuring that the sleeve block 61 can move flexibly on the sliding plate 5. A threaded hole 15 is provided on the bottom surface of the sleeve block 61, designed to fit the dimensions of the lead screw 81. A threaded block 16 is threadedly connected inside the threaded hole 15, matching the specifications of the threaded hole 15 to ensure a stable connection. An adjustment bolt 62 is threaded through the upper surface of the sleeve block 61, with a head designed for easy tool operation. Its specifications are adapted to the threaded hole on the sleeve block 61. The lower end of the adjustment bolt 62 is rotatably connected to the connecting block 63 via a bearing. This bearing can withstand a certain load to prevent damage during adjustment. Multiple first connecting seats 64 are fixedly provided on the side wall of the connecting block 63, evenly distributed on the side wall of the connecting block 63 to ensure balanced force distribution. One end of the first connecting seat 64 is rotatably connected to the connecting plate 65 via a pin, possessing a certain degree of elasticity to buffer force during transmission. One end of the connecting plate 65 is rotatably connected to the second connecting seat 66 via a pin. The second connecting seat 66 and the guide rod 67 are integrated into a single design to enhance connection strength. One end of the second connecting seat 66 is fixedly connected to the guide rod 67, and its surface is treated to ensure smooth sliding. One end of the guide rod 67 passes through the sleeve block 61 and extends to the outside to be fixedly connected to the limiting plate 68. The shape of the limiting plate 68 is designed according to the shape of the guide groove 14. Its surface is provided with an anti-slip structure to increase the friction with the inner wall of the guide groove 14. It can drive the linkage block 63 to move by rotating the adjusting bolt 62. The linkage block 63 drives the limiting plate 68 at one end of the guide rod 67 to move simultaneously through the first connecting seat 64, the linkage plate 65 and the second connecting seat 66. The limiting plate 68 is set with an arc-shaped structure. The guide groove 14 and the limiting plate 68 are slidably connected, which can make the limiting plate 68 stably contact the inner wall of the guide groove 14, thereby limiting the sleeve block 61 and realizing the precise adjustment of the cable tray installation angle.

[0026] like Figure 3 , Figure 4 and Figure 6As shown, a positioning component 8 for supporting the cable tray is located directly below the adjusting component 6. The positioning component 8 includes a set of lead screws 81 fixedly mounted on the bottom surface of the socket block 61. The lead screws 81 are rust-proofed and their specifications are compatible with the threaded block 16. One end of the threaded block 16 is fixedly connected to the lead screw 81. After connection, it is ensured to be defect-free. The lead screw 81 can be easily disassembled and assembled through the cooperation of the threaded block 16 and the threaded hole 15, facilitating later maintenance and replacement. A socket mounting seat 82 is movably sleeved on the outer wall of the lead screw 81. The inner wall of the socket is provided with a through hole adapted to the lead screw 81. The inner wall of the through hole is lubricated to reduce friction with the lead screw 81. A transmission roller 83 is rotatably mounted between the socket mounting seats 82 via bearings. The outer layer is provided with a structure that is elastic and wear-resistant. The transmission roller 83 can provide support during the installation of the cable tray, allowing the cable tray to slide and reduce friction, thereby improving installation efficiency. The length of the transmission roller 83 is adapted to the width of the cable tray, ensuring that the cable tray can slide stably on the transmission roller 83. The outer wall of the lead screw 81 is threaded with a limiting nut 84, the surface of which is rust-proofed. The limiting nut 84 is located below the sleeve mounting base 82. The limiting nut 84 can limit the sleeve mounting base 82 and facilitate the adjustment of the position of the sleeve mounting base 82 on the lead screw 81 to meet the support requirements of cable trays of different heights.

[0027] Furthermore, the outer wall of the lead screw 81 is movably fitted with a limiting block 17. The bottom surface of the limiting block has an anti-slip structure that protects the cable tray surface, increasing friction while preventing scratches. The shape of the limiting block 17 is designed according to the cross-sectional shape of the cable tray to ensure a tight fit. A positioning nut 18, identical in specification to the limiting nut 84, is threaded onto the outer wall of the lead screw 81, facilitating consistent tool operation. The positioning nut 18 is located above the limiting block 17, limiting its position and ensuring stable installation, preventing displacement or shaking during installation.

[0028] The working principle of this embodiment is as follows: First, the insert 4 on the frame 3 is aligned and inserted into the insertion hole 2 on the mounting rib 1. After insertion, the first through hole 9 on the mounting rib 1 coincides with the second through hole 10 on the insert 4, and the frame 3 is stably fixed and limited on the mounting rib 1 by the mounting bolt 11.

[0029] Subsequently, the adjusting screw 7 is manually rotated, and the screw 7 engages with the threaded connection of the frame 3, causing the sliding plate 5 to slide along the bottom surface of the frame 3. During this process, the sliding grooves 13 on both sides of the sliding plate 5 and the guide grooves 12 on the bottom surface of the insert 4 form a sliding engagement, ensuring that the sliding plate 5 always moves in a straight line and avoids deviation.

[0030] After the sliding plate 5 moves to the appropriate position, the threaded block 16 is rotated and inserted into the threaded hole 15, so that the lead screw 81 is stably connected to the bottom surface of the sleeve block 61. Then, the cable tray to be installed is placed on the transmission roller 83 between the lead screw 81 and the cable tray is pushed. The cable tray will drive the transmission roller 83 to rotate on the sleeve mounting seat 82 by its own weight. With the guidance of the transmission roller 83, the cable tray can be easily pushed to adjust the installation position, which greatly reduces the friction between the cable tray and the installation structure and reduces the manpower consumption during the installation process.

[0031] Next, when adjusting the installation angle of the cable tray, manually rotate the adjusting bolt 62 on the upper surface of the sleeve block 61. Since the lower end of the adjusting bolt 62 is rotatably connected to the connecting block 63, the rotation of the adjusting bolt 62 will drive the connecting block 63 to move vertically downward. The connecting block 63 drives the connecting plate 65 to move through the first connecting seat 64. The connecting plate 65 drives the limiting plate 68 at one end of the guide rod 67 to move through the second connecting seat 66, so that the limiting plate 68 is away from the guide groove 12 on the sliding plate 5.

[0032] Next, the rotating sleeve block 61 drives the lead screw 81 to rotate through the threaded hole 15 and the threaded block 16. The lead screw 81 drives the cable tray to change its installation position through the sleeve mounting seat 82 and the transmission roller 83. After adjusting to the appropriate angle, the adjusting bolt 62 is rotated in the opposite direction. The rotation of the adjusting bolt 62 will drive the connecting block 63 to move vertically upward. The connecting block 63 drives the connecting plate 65 to move through the first connecting seat 64. The connecting plate 65 drives the limiting plate 68 at one end of the guide rod 67 to move through the second connecting seat 66, so that the limiting plate 68 is in close contact with the guide groove 12 on the sliding plate 5, thereby limiting the sleeve block 61.

[0033] Finally, the positioning nut 18 pushes the limiting block 17 to move vertically downward on the screw 81, so that the bottom surface of the limiting block 17 contacts the upper surface of the cable tray. The positioning nut 18 limits the limiting block 17, thereby preventing the cable tray from shaking or displacing.

[0034] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
